Anyone had this issue and figured out how to fix it?

Issues comes intermittently after I disconnect battery it will be okay for a day or 2 before starting again.

Changed the tcm and still doing the same thing.

Any feedback would be appreciated. Video link below

Thanks in advance!

Try and give the harness a good tug and wiggle/ inspection for damage. Disconnect connections and look for corrosion. Code is very generic could be anywhere.
